Research a way to bulk upload emoticons required for Gamebot

[johnbeech]

There's a list.emoji's command:

• https://api.slack.com/methods/emoji.list

But not obvious way to upload emojis outside of the web form:

• https://resistance-gamebot.slack.com/admin/emoji

Possibly this is a solution (Chrome Plugin - Bulk Emoji Uploader):

• https://chrome.google.com/webstore/detail/slack-emoji-tools/anchoacphlfbdomdlomnbbfhcmcdmjej

Renamed icons to emojis folder, and added script to create an index.
